Yeah, libraries suck.  I just try to avoid using one of the PC's at my parent's house because they'd probably start filtering/blocking almost everything...that's what they did to my brother.
Anyways, by 'fluctuate' I don't mean waves, but the whole screen still changing contrast for a second or two before settling to a neutral shade.  Think of it like plucking a rubber band and it vibrates for a minute or so.  The contrast level 'vibrates' for a bit before settling.

I'll try to get a video of it soon (once I find my SD card for the camera).

I've just been messing around, but this time it actually yielded something.

One is a pixel that bounces around a defined border, creating some interesting effects and patterns.
The other program lets you experiment with sound

up\down: change pitch
left\right: change length
trace\graph: change interval

It was the second one, with the Shade( command.

Got to go, my library session's about to time out.  I should be able to get back on around noon tomorrow.

I don't know how it worked, but something i did made the screen turn blue, but I can't remember what it was...

EDIT....
here it is

Repeat 1=2
If getKey=15
Goto E
End
-1→B
62→A
Repeat A>62
Shade(A)
A+B→A
If A<1
-B→B
End
End
End
Lbl E
Shade(47)

I got the same bug as Magic Banana. I'm using 84+ (BE) os 2.43 and I got the 'gray level' question the first time, then it displayed these random lines and what looks like cut-up zeros. On 0.2.6 it spat out a symbol error at 3% while compiling...
For the record, the ALCDFIX program (http://www.ticalc.org/archives/files/fileinfo/366/36608.html) didn't work. 
Might Spr-2-Hex at http://www.ticalc.org/archives/files/fileinfo/397/39717.html work, by any chance?
